• Antarctic scientists have trialed a DNA “barcoding” technique that could improve biosecurity measures that help protect polar ecosystems from invasive marine species. • The research, led by Australian Antarctic Program scientists, used environmental DNA (eDNA) in water samples to detect species known to hitchhike on ships’ hulls.
Article Summaries:
- Antarctic researchers have tested a new DNA‑barcoding method that could strengthen biosecurity in polar waters. Using environmental DNA (eDNA) collected from seawater, the Australian Antarctic Program team identified species that commonly attach to ships’ hulls and could become invasive. The trial demonstrates that eDNA sampling can detect these hitchhikers early, potentially allowing authorities to intervene before they establish in fragile ecosystems. The study highlights the technique’s promise for monitoring and protecting Antarctic marine habitats from non‑native species introduced via global shipping.
